Health-related quality of life (HRQL) is an accepted outcome measure in patients with mood and anxiety disorders. Yet, surprisingly little attention has been paid to the determinants. In this paper we test the hypothesis that it is associated with personality traits while controlling for mental disorders.
A large sample of outpatients (n = 640) with mood and anxiety disorders was studied. The empirically supported five factor model of normal personality traits was assessed using the NEO-FFI and includes: neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness. Mental disorders were assessed with the CIDI, and HRQL with the SF-36.
Regression analyses revealed that the NEO-FFI scores, with the exception of conscientiousness, were significantly associated with SF-36 subscales and summary scores, independently from the mental disorders. The percentage of explained variance due to the personality traits was highest for the subscales Vitality (10.0%), Mental Health (13.3%) and the Mental Health Summary Score (9.5%). Furthermore, specific personality traits were related to specific SF-36 subscales.
A low HRQL of patients with mood or anxiety disorders is not only determined by the disease or the current health but is also shaped by personality traits that are relatively stable throughout an individual's life time.
健康相关生活质量(HRQL)是心境障碍和焦虑症患者公认的结局指标。然而,令人惊讶的是,人们对其决定因素关注甚少。在本文中,我们检验这样一个假设,即在控制精神障碍的同时,它与人格特质相关。
对一大样本(n = 640)患有心境障碍和焦虑症的门诊患者进行研究。使用NEO-FFI评估经验证支持的正常人格特质五因素模型,该模型包括:神经质、外向性、开放性、宜人性和尽责性。使用CIDI评估精神障碍,使用SF-36评估HRQL。
回归分析显示,除尽责性外,NEO-FFI得分与SF-36分量表及总分显著相关,且独立于精神障碍。人格特质导致的方差解释百分比在活力分量表(10.0%)、心理健康分量表(13.3%)和心理健康总分(9.5%)中最高。此外,特定的人格特质与特定的SF-36分量表相关。
心境障碍或焦虑症患者的低HRQL不仅由疾病或当前健康状况决定,还受到个体一生中相对稳定的人格特质的影响。
